MEANS ,USABLE WITH MECHANIC I KL TELEGRAIEHS FOR SHIPS.

Application filed September 13,'1922. Serial no. 587,898.

Toall whom it may conceme' 'Be it known that I, JOHN STANLEY WIL- soN, a subject of the King of Great Britain and Ireland, residing at 255 Johnston Street, Annandale, near Sydney, New South Wales, Australia, have invented certain new and useful Means Usable WithMechanical Telegraphs for Ships, of which the" following is a specification. 1' I This invention relates to means which areusable in connection with mechanical telegraphs for ships; the object of thein vention is to provide means whereby it will:

be ensured that. the orders'transmitted 'by the pilot to the-engineerthrough the operation of the telegraph will receivecorrect' attention. Said meansmav-be used for indicating to theengineer whether the orders transmitted to him from the correctly attended to:

The said means comprise apparatus 'associated with the telegraph order dial "located in the engine-"roomandalsoi-with the-con tro l lever or, the like for".regulating the niotion oftheengine; said means may also comprise independent signalling apparatus,-

9 is a substantially vertical sectional, view taken through the shutter and associated parts; i

With reference to Figs. 1' to! cessed frame 1 is providedflwith ad ap m' m 2. Either one ofthe'pulleys. 3 orxtfiized to the sleeves 5 and/6 inay'be connected by a cord or chain to. the spindle 'of the receiver pointer of the order dial located inthe en; gine room. If the pulley 4 is so connected the other pulley is connected to the lever I I y V the left jthero'ller 161' will be brought into connecting the receiver telegraph dial 66 pilot have been 7 i v V t (be connected to-the' spindle. or the pointer carries at its head a contact roller 8. Similarly on bothsides of the diaphragm 2' are awpair'oflevers. 9 and 10. The levers 10 have pivoted to their head one end of a reciprocahle cam-lever 11. Such camlevers contactrespectively with rollers 12 carried" on the lhottom of sliding rods 13 (one'foreach.camdever 11) which may be "made to project through j openings in the head of the .rfr'anle 1 depending on "the movements imparted to the" cam levers 11 j byflthe 'operation of the levers 9 and 10 and the: lever '7. v

Integral with the Sleeves 5 and 6 respectively; are a-rinsrlt and 25 which respec-.

tively carry rollersf15 and16. Such sleeves are rotatably mounted on a spindle 17 which is rigidlyfixedtorthe diap'hragInQ; The levers -7 arepivotally' sup-ported on pins 18 secured to opposite sides of said diaphragm. stopypins' l9affixed-jto the diaphragm fl are provided 'for'the' levers 7' an'd 10. Leaf springs 20 and 21 serve to keep the levers '7 and 9 innormal position"asshown in Fig. f

2 such springs may be suspended, from pins QQ attaCheidtethe dia'phragm'2. One end of lone of the levers 9 at one'sideof the dia- 'phragmQi isfixed, to one end of the rotatable spindle 23;;the opposite end of said.

spindle has fixedto .it on the opposite side Of sa'iddiaphragm one end otone of the levers 10. The other.lever,'9"is fixed at one 'end'fto one. end of a rotatable sleeve 24;

whose otherrend has fixed .to it one end of V the other lever 10. The arrangement of the levers 9 andlO on the spindle 23 and sleeve 24: shown in'FigA." .Cover plates 31 may heprovidedxfo-rthe frame 1 if required.

' In'operation, assuming the pulley e to dial located in the engine room which.

pointer is moved by the pilot operating the telegraph; thef'arin 25 will be swung either to theri ght or to theileft by the pilot when operating the telegraph to communicate his signals to the'"engineerL'; if it is moved to contactwith lever 9 on that side of the diaphragm "2 on which the pulley 4 is located and such lever 9 will be moved sidemoved 1111 a direction opposite to that of wardly'against the pressure thereon of the spring 21. Assuch lever 9 is afiixed to the spindle 23 (see-Fig. 4) one of the levers;

10 on the opposite side of the diaphragm 2 towhich the'pulley 4 is located will be said lever 9 and consequently the cam-lever 11 associated with said lever 10 will be moved in the direction of movement of sald lever 10. During such movements of the levers 9 and 10 and the said ca m-lever 11 the levers 7 and the other cam-lever 11 remain stationary V p L i As the. sleeve 6 is associated with the pulley 4 and the other sleeve 5 is associated with the pulley Bend the pulley 4 is assumed to be connected to the receiver pointer dial, if thefengineer should by error (aftermovements have rbeen communicated as above described to-the said levers) swing the arm 14 so as to bring theroller 15 into con-,

tact with the lev'er 7 on that side of the dia-' phragm on which the pulley 3 is located which the-pulley3 is located. Suchjroller 8 when it islhrought into engagement with the swelling 26; on the'saidcam lever 11} raises said lever and also raises simultaneously the sliding. rod 13 in fcontact therewith throughf the roller 12. The sliding rod l3 on the side of the diaphragm 2 on whichthe pulley 4 is 2 located is not, however, raised but remains stationary, consequently the engineer will have a visible indication by the .upper end of V the said rod 13 (which has been moved) being above the. other rod 13 that he has given j motionto' the enginein a direction contrary to the order telegraphed to him bythe pilot. The levers 9 may be arranged for ahead orders andthe levers .7 for astern or p ter'-54is' a slider "60 engaging the guide ders or, vice versa'. is

Referringto Figs. 5 to 9, means are shown therein associated with the frame '1 and the lever 27 whereby avisual and an audible signal may be-givento the engineer in case he should operate the control lever of the'engine contraryto the instructions transmittedto him (on the receiver dial ofthe telegraph); from the pilot. In Fig. 5 the pulley 3 is assumed to be connected by the cords'30 and the chains 32' tothe shaft 34 to which the control lever or the like of the engine is fixed and the pulley 4. is similarly connected by the cords 33. andgchains similar to the chains 32 to the receiver pointer dial oiithe telegraph located in the engine room. The chains 32 are shown attached respectively tothe shaft34 and to the'pul At'vone side of the of the cords 30 may be attached to lugs 35 on oppositesideslof a collar-36 fitting the shaft; 34 and detachably fastened thereto by means ofa pinching screw 64. A pinching screw '37 i also serves to connect the chains 32 to*the pulley.3.

framel is a bracket 38 having pivoted thereto by a pin 39 a countel-weighted lever 40; this lever has pivoted to it one endof alink 41 whose other end is pivoted to the lever 27. Another bracket 42 extends from the head of the frame .1 and carries at its outer end arbell 43; said bracket also has attached thereto by means of pins '46 leaf springs 44 and 45 located,

onopposite sides of a pivoted striker lever 47 for the bell 43. Associated with said lever47 isa push lever 48 whose outer end slightly overlapsthe end 49 of the lever 47 theiorward end of said lever 48 is pivoted .to the bracket 42 and its other end is pivotally connected to a lug 50 on the lever 27'. Upon the upward movement of the lever 27 the lever 48.tilts the lever 47 against the pressure of the spring 44 and when said lever 48' passes the end of the lever 47 it (the 43. The lever 47 subsequently returns to normal position whereby one of its. sides will be in contactwith the spring 45. Abut-i 1 ment pins 51 and 52 are provided on the bracket '42gfor the springs 44 land .45.;

Sirnultaneously with V the audible I signal conveyed to the engineer by the bell43 the link 41 raises the lever 40 whose free end is I 3 connected by spit cred link 53 to a drop shutterb 54 carried in .a casing within full,

view of the vengineer. The said casing is rigidly attached by means of lugs :56 thereon to asupporting pillar 57,. andits face 7 55"-carries two pins 58 whichpins whilst serving to attach the face 55 to a guide plate 59 also serve tol distance such plate from saidfface. Attachedto the head of the shut- 7 plate. 59'; said slider has affixed thereto a plate 61 tofwhich the foot of the link53 is pivoted. f To prevent the lever 40 and the spring- 62 carried on the bolt 63 attached-to the bracket 38 maybe provided. Wording such as Wrong movement or other suit ableindicating words may appear on the shutter 54' descending too far the wire 7 face ofthe shutter-54L Return of the lever 40 to normal position as shown in Fig.5 is I rod s13 is not operated through the engineer 3 moving the shaft 34 to control movements of the; engine in accordance with instruc-.

tions transmitted to him by the pilot the cooperating mechanism of the bell 43 and the shutter 5% will not be operated by the lever 27. Any up ward movement of either of the rods 13 will, however, move the lever 27 and consequently the said bell and shutter signals will be given to the engineer.

The lever 27 and the pulleys 3 and 4 have been omitted from Fig. 1 of the drawings for the purpose of allowing certain parts of the apparatus to be clearly seen.
